Patients will receive the current standard of care, as per the anaesthetist in charge, with regards to temperature monitoring, and the use of passive/active warming strategies. The method of temperature monitoring, warming or heat conservation techniques would be recorded and the patient's temperature would be measured at the recovery area post-operatively by the recovery nurse. In addition, patient demographics, surgical time, anaesthetic time, surgical procedure and method of anaesthetic, total fluids given, will also be recorded on a prospectively-designed data collection form.
